Railfan Special Sponsored by the Philadelphia Chapter National Railway Historical Society. The special train (includes schedule) from Philadelphia to Annapolis Maryland and return to Philadelphia. The trip was over Baltimore & Ohio RR and in particular sections of the Baltimore & Annapolis RR. Early railfan special train. May 1, 1949. Unfolded, the poster measures 19" x 5 1/2". Ideally the poster should be framed or stored completely flat. Shipping will be via Ground Advantage Mail with a cardboard reinforced envelope with the poster folded in half (existing fold). I will also consolidate orders, if requested, to save on shipping costs.
